Abstract: ABSTRACT OF THE DISCLOSURE         The invention relates to tube panels having vertical pipes which are adapted to be cleaned by vibrations.  The panels consist of vertical pipes mounted between a lower distributor and an upper collector.  Elastic input and output pipes connect the vertical pipes to the distributors and collectors, respect-ively, and these pipes are bent out of plane of the vertical pipes.  In this manner, the vertical pipes can he vibrated, the vertical pipes of the panels can extend to the entire height of gas flue, and neither the construction nor the arrange-ment of the other structural elements of the heat exchanger, wherein the vertical pipes are built in, are either complicated or hindered by them.

Abstract: Injection Type Lubricating Apparatus Abstract Pump body has a cylindrical chamber within which a spool-shaped insert fits.  The insert has a central cylindrical bore within which the injection plunger works and has an external annular groove com-municating with the bore through a lubricant supply port having a diameter smaller than that of the bore.          Lubricant is furnished to the bore through an opening in the pump body which communicates into the annular space defined by the insert groove.  The fit between the plunger and bore is interrupted only through the arcuate extent of the diameter of the lubricant supply port.

Abstract: ABSTRACT OF THE DISCLOSURE    In a cabin pressure control system utilizing dual controllers, one of which is in primary control of cabin pressure and the other of which is standby, external pressure and cabin pressure are monitored.  If the differ-ence exceeds a predetermined safe value, the rate of change of cabin pressure is incremented based on the excess.  Also, switching of control from the primary to secondary controller, as would occur upon malfunction, is prevented.

Abstract: Abstract of the Disclosure A crimped yarn product comprises a textured continuous filament yarn produced by feeding the yarn at a controlled rate and under controlled tension by a pair of feed rolls into a confined crimping zone against a mass of crimped yarn therein, causing the yarn to collapse longitudinally to form crimps which become part of such mass.  Heat and pressure are applied to the yarn mass in the crimping zone to plastically deform the yarn and partially set the crimps.  The crimped yarn mass is then fed at a controlled rate by means of toothed rolls from the crimping zone into a setting zone and the yarn mass is transported through the setting zone.  Heat and pressure are applied to the yarn mass in the setting zone to fully set the crimps.  The pressure applied to the yarn mass in the setting zone is substantially suf-ficient only to keep the crimps closed during the final setting thereof.  The yarn mass is cooled in the cooling zone to a temperature below that at which the yarn undergoes any molecular structural alteration in the absence of the application of a substantial force thereto.  Finally, the yarn is withdrawn at a controlled rate from the cooling zone in continuous filament form.

By the reaction, isopropenylphenol and/or its oligomers are introduced to the drying oil while the double bonds of the oil are retained.  The thus introduced oil is further reacted with a phenol or phenols under strongly acidic conditions to introduce the phenols thereto.  The drying oil which has been introduced with the isopropenylphenol and/or its oligomers and also with the phenols is mixed with a phenol or phenols and then reacted with formaldehyde to give a modified phenolic rosin. This phenolic resin is useful for making a phenolic laminate with improved flexibility punching quality and water resistance.

Abstract: 17                       47,406 ABSTRACT OF THE DISCLOSURE A system for reducing the bandwidth and simul-taneously transmitting a plurality of signals through a common transponder is disclosed.  The system is particu-larly useful for the transmissions of multiple TV signals via a geostationary satellite.  Prior to transmission the bandwidth of  each of the signals to be transmitted is reduced by  one half by  deleting  every other  line  and expanding  each of  the remaining lines to cover a time interval normally occupied by two lines.  After transmis-sion through the satellite, each of lines is recorded at a first rate and read back at a higher rate to reduce the time interval of each line to its original value.  Each line is repeated twice to reconstruct a TV signal having the same format as the original signal.

Abstract: Abstract A noise blanker which has circuitry that enables the threshold level of noise blanking to track the average background noise level is disclosed.  In general, a control-lable gate receives an input signal and selectively passes and blocks the input signal in response to received noise blanking pulses which are generated in response to high peak magnitude noise impulses.  A signal related to background and impulse noise is extracted from an input signal.  A controllable gain noise amplifier is utilized to amplify the separated background and impulse noise and negative feedback circuitry is utilized to maintain the average peak output of the noise amplifier substantially constant except for occasional large magnitude noise impulses which do not substantially change the average peak magnitude of the background and impulse noise.  The output of the controll-able noise amplifier is applied to a threshold switch means which produces blanking pulses in response to the amplified noise signal having a peak exceeding a magnitude which is greater than the substantially constant peak output level of the noise amplifier.  This results in a blanker circuit in which the threshold level of blanking pulses closely tracks the average peak value of the background and impulse noise.
